Modified files:
bin/expr expr.1 expr.y
Log:
The response to my POSIX interpretation request says that `expr'
is required to be oblivious to overflow and to use the data type `long'.
(Division by zero is undefined in ISO C so it's still OK to check for it
here.) Add a new `-e' flag to get the old, more useful behavior.
